115810 AUTOMAATTINEN TEHONOHJAUSJÄRJESTELMÄ KOODIJAKOISESSA MONILIITTYMÄISESSÄ (CDMA) TIETOLIIKENNEJÄRJESTELMÄSSÄ115810 AUTOMATIC POWER CONTROL SYSTEM IN CODE-DIVISION MULTI-INTERFACE (CDMA) COMMUNICATION SYSTEM
Keksinnön tausta 5BACKGROUND OF THE INVENTION 5
Laadukkaiden tietoliikennepalvelujen järjestäminen käyttäjäryhmille, jotka on luokiteltu kaukaisina, kuten maaseudun puhelinjärjestelmät ja puhelinjärjestelmät kehitysmaissa, ovat osoittautuneet olevan haaste viime vuosina. Nämä tarpeet on osittain tyydytetty langattomilla radiopalveluilla, kuten kiinteät tai liikku-10 vat taajuusjakoiset multipleksi- (FDM), taajuusjakoiset moniliittymä- (FDMA), aikajakoiset multipleksi- (TDM), aikajakoiset moniliittymäjärjestelmät (TDMA), yhdistelmä taajuus- ja aikajakoiset järjestelmät (FD/TDMA), ja muut liikkuvat maaradiojärjestelmät. Tavallisesti, nämä kaukaiset palvelut kohtaavat enemmän mahdollisia käyttäjiä kuin voidaan tukea samanaikaisesti niiden taajuus- tai 15 spektritaajuusleveyden kapasiteetilla.Providing high-quality telecommunications services to groups of users classified as remote, such as rural telephone systems and telephone systems in developing countries, has proven to be a challenge in recent years. These needs are partially met by wireless radio services, such as fixed or mobile frequency division multiplexing (FDM), frequency division multiple access (FDMA), time division multiple access (TDM), time division multiple access (TDMA), combination frequency (DMA) and / TDMA), and other mobile terrestrial radio systems. Typically, these remote services will face more potential users than can be supported simultaneously with their frequency or spectrum bandwidth capacity.
Tunnistamalla nämä rajoitukset, viimeaikaiset edistysaskeleet langattomassa tietoliikenteessä ovat käyttäneet hajaspektrimodulaatiotekniikoita antamaan samanaikaisen yhteyden usealle käyttäjälle yhden tietoliikennekanavan kautta.Recognizing these limitations, recent advances in wireless communications have used spread spectrum modulation techniques to provide simultaneous access to multiple users over a single communication channel.
20 Hajaspektrimodulaatio viittaa informaatiosignaalin modulointiin levittävällä koo- disignaalilla; joka levittävä koodisignaali on generoitu koodigeneraattorilla, jossa | levityskoodin aikajakso Te on olennaisesti lyhyempi kuin informaatiodatabitin tai symbolisignaalin aikajakso. Koodi voi moduloida kantoaaltotaajuutta, jolle in- :*V formaatio on lähetetty, jota kutsutaan taajuushyppäyslevitykseksi, tai voi suo- • · · ;;··* 25 raan moduloida signaalin kertomalla levitetyn koodin informaatiodatasignaalilla, : jota kutsutaan suorasekvenssilevitykseksi (DS). Flajaspektrimodulaatio tuottaa • · · ·' signaalin, jolla on kaistanleveys, joka on olennaisesti suurempi kuin vaaditaan lähettämään informaatiosignaali. Synkroninen signaalin vastaanotto ja kaven-:Y: taminen vastaanottimen demodulaattorissa palauttaa alkuperäisen informaati- 30 on. Synkroninen demodulaattori käyttää referenssisignaalia synkronoimaan ka-, vennuspiirit sisääntulon hajaspektrimoduloituun signaaliin palauttamaan kanto-aallon ja informaatiosignaalit. Referenssisignaali voi olla hajotuskoodi, jota ei > · 1 · · · * ole moduloitu informaatiosignaalilla.Spread spectrum modulation refers to modulation of an information signal by a spreading code signal; which propagating code signal is generated by a code generator where | the spreading code time period Te is substantially shorter than the information data bit or symbol signal period. The code may modulate the carrier frequency to which the in-: * V information is transmitted, known as frequency hopping spreading, or may modulate the signal by multiplying the spread code by an information data signal: called direct sequence spreading (DS). Flame spectrum modulation produces a · · · · 'signal having a bandwidth substantially greater than that required to transmit the information signal. Synchronous signal reception and narrowing: in the receiver demodulator returns the original information. The synchronous demodulator uses a reference signal to synchronize the gain, gain circuits to the input spread spectrum modulated signal to recover the carrier and information signals. The reference signal may be a spreading code which is not> · 1 · · · * modulated by an information signal.
35 Hajaspektrimodulaatio langattomissa verkoissa tarjoaa monia etuja, koska useat käyttäjät voivat käyttää samaa taajuuskaistaa minimi-interferenssillä kunkin käyttäjän vastaanottimeen. Lisäksi, hajaspektrimodulaatio pienentää vaikutuksia 2 115810 muista interferenssilähteistä. Myöskin, synkronisia hajaspektrin modulaatio- ja demodulaatiotekniikoita voidaan laajentaa antamalla useita viestikanavia käyttäjälle, kukin levitettynä eri levityskoodilla, samalla kun lähetetään vain yksi refe-renssisignaali käyttäjälle.35 Spread spectrum modulation in wireless networks offers many advantages because multiple users can use the same frequency band with minimum interference to each user's receiver. In addition, spread spectrum modulation reduces the effects of 2 115810 from other sources of interference. Also, synchronous spread spectrum modulation and demodulation techniques can be expanded by providing multiple message channels to a user, each spread with a different spreading code, while only transmitting one reference signal to the user.

Toinen monijakoisiin, hajaspektritietoliikennejärjestelmiin liittyvä ongelma on tarve pienentää käyttäjien yhteistä lähetettyä tehoa järjestelmässä, kun käyttäjillä voi olla rajoitettu käytettävissä oleva teho. Liittyvä ongelma, joka vaatii te-honohjausta hajaspektrijärjestelmissä liittyy mukana olevaan hajaspektrijärjes-10 telmien ominaisuuteen, että yhden käyttäjän hajaspektrisignaali on vastaanotettu toisella käyttäjällä kohinana tietyllä tehotasolla. Vastaavasti, käyttäjät, jotka lähettävät suurilla signaalintehon tasoilla, voivat häiritä muiden käyttäjien vastaanottoa. Myös, jos käyttäjä liikkuu suhteessa toisen käyttäjän maantieteelliseen sijaintiin, signaalin häivyntä ja särö vaativat, että käyttäjät sovittavat hei-15 dän lähetystehotasonsa ylläpitämään tietyn signaalin laadun, ja ylläpitämään tehon, jonka tukiasema vastaanottaa kaikilta käyttäjiltä. Lopuksi, koska on mahdollista, että hajaspektrijärjestelmässä on enemmän käyttäjiä, kuin voidaan tukea samanaikaisesti, tehonohjausjärjestelmän pitäisi myös käyttää kapasiteetin hallintamenetelmää, joka hylkää lisäkäyttäjät, kun järjestelmän maksimitehotaso 20 on saavutettu.Another problem with multipath spread spectrum communication systems is the need to reduce the total transmitted power of the users in the system when users may have limited available power. A related problem requiring power control in spread spectrum systems is related to the inherent feature of spread spectrum systems that one user spread spectrum signal is received by another user as noise at a given power level. Similarly, users transmitting at high signal power levels may interfere with the reception of other users. Also, if a user is moving relative to another user's geographic location, signal fading and distortion require users to adjust their transmit power level to maintain a particular signal quality, and to maintain the power received by the base station from all users. Finally, since it is possible that the spread spectrum system has more users than can be supported simultaneously, the power control system should also use a capacity management method that rejects additional users when the system maximum power level 20 is reached.
• · ! !. Entiset hajaspektrijärjestelmät ovat käyttäneet tukiasemaa, joka mittaa vas- ;*Y taanotetun signaalin ja lähettää sovittavan tehonohjauksen (APC) signaalin : kaukaisille käyttäjille. Kaukaiset käyttäjät sisältävät lähettimen, jossa on auto- 25 maattinen vahvistuksen ohjauksen (AGC) piiri, joka vastaa APC-signaaliin.• ·! !. Former spread spectrum systems have used a base station that measures the received * Y signal and transmits the adaptive power control (APC) signal: to remote users. Remote users include a transmitter having an automatic gain control (AGC) circuit which responds to the APC signal.
; ’·· Sellaisissa järjestelmissä tukiasema valvoo järjestelmän kokonaistehoa tai te- ν’ i hoa, joka on vastaanotettu kultakin käyttäjältä, ja asettaa APC-signaalin vastaa vasti. Tätä avoimen silmukan järjestelmän suorituskykyä voidaan parantaa si-säilyttämällä signaalitehon, jonka kaukainen käyttäjä on vastaanottanut tu-30 kiasemalta, mittaus ja APC-signaalin lähettäminen takaisin tukiasemalle ai-.* . kaansaamaan suljetun silmukan tehonohjausmenetelmä.; In such systems, the base station monitors the total system power or power received from each user and sets the APC signal accordingly. This performance of the open-loop system can be improved by retaining measurement of the signal power received by the remote user from the base station and transmitting the APC signal back to the base station ai -. *. to gain a closed-loop power control method.
Nämä tehonohjausjärjestelmät, kuitenkin, näyttävät useita epäkohtia. Ensiksi, tukiaseman täytyy suorittaa monimutkaisia tehonohjausalgoritmeja, lisäten pro-35 sessoinnin määrää tukiasemalla. Toiseksi, järjestelmä todellisuudessa kokee useita tehonvaihtelun tyyppejä: vaihtelu kohinatehossa, jonka aiheuttaa käyttäjien vaihtuva määrä, ja vaihtelut erityisen kantajakanavan vastaanotetussa sig- 3 115810 naalitehossa. Nämä vaihtelut sattuvat eri taajuudella, joten yksinkertaisia te-honohjausalgoritmeja voidaan optimoida vain yhteen kahdesta vaihtelun tyypistä. Lopuksi, nämä tehoalgoritmit pyrkivät ohjaamaan järjestelmän kokonaiste-hon suhteellisen suurelle tasolle. Vastaavasti, on tarve hajaspektritehonoh-5 jausmenetelmälle, joka nopeasti vastaa muutoksiin kantajakanavan tehotasois-sa, kun tekee samanaikaisesti sovituksia kaikkien käyttäjien lähetystehoon vasteena muutoksiin käyttäjien määrässä. Myöskin, on tarve parannetulle haja-spektritietoliikennejärjestelmälle, joka käyttää suljetun silmukan tehonohjausjär-jestelmää, joka minimoi järjestelmän kokonaistehovaatimukset, kun se ylläpitää 10 riittävän BERin yksittäisissä kaukaisissa vastaanottajissa. Lisäksi, sellaisen järjestelmän tulisi ohjata kaukaisen käyttäjän aloituslähetystehotasoa ja hallita järjestelmän kokonaiskapasiteettia.These power control systems, however, show several drawbacks. First, the base station must perform complex power control algorithms, increasing the amount of pro-35 processing at the base station. Second, the system actually experiences several types of power fluctuations: fluctuations in noise power caused by a variable number of users, and fluctuations in the received signal power of a particular carrier channel. These fluctuations occur at different frequencies, so simple power control algorithms can be optimized for only one of two types of fluctuations. Finally, these power algorithms tend to control the overall system power to a relatively high level. Similarly, there is a need for a spread spectrum power management method that responds rapidly to changes in carrier power level while simultaneously adapting the transmission power of all users in response to changes in the number of users. Also, there is a need for an improved spread spectrum communication system utilizing a closed-loop power control system that minimizes overall system power requirements while maintaining 10 sufficient BERs at individual remote receivers. In addition, such a system should control the remote user's initial transmit power level and manage the total system capacity.

Esimerkinomaisessa sovellutusmuodossa, yksi radiolinkki on kuvattu 5 tukiasemalle kommunikoiden kiinteän tilaajayksikön (FSU) kanssa, mutta järjestelmä on vastaavasti sovitettavissa järjestelmiin, jotka sisältävät monia tukiasemia, joissa on radiolinkit sekä FSU:ille että matkatilaajayksiköille (MSU:t). Vastaavasti, kaukaisiin tilaajayksiköihin viitataan tässä tilaajayksikköinä (SU:tt).Description of the Exemplary Embodiment The system of this invention provides a local loop telephone service using a radio link between one or more base stations and a plurality of remote subscriber units.

5 CDMA-modulaattori joko RCSissä tai SU:ssä kaventaa vastaanotettua signaalia sopivalla prosessoinnilla poistaakseen tai hyödyntääkseen monitie-etenemisen vaikutuksia. Parametrejä, jotka koskevat vastaanotettua tehotasoa, käytetään generoimaan automaattisen tehonohjauksen (APC) informaatiota, joka, vuoros-10 taan, lähetetään toiseen päähän. APC-informaatiota käytetään ohjaamaan automaattisen myötätehonohjauksen (AFPC) ja automaattisen vastatehonohjauk-sen (ARPC) linkkien lähetystehoa. Lisäksi, kukin RCS 104, 105 ja 110 voi suorittaa ylläpitotehonohjauksen (MPC), samalla tavalla kuin APC, sovittamaan kunkin SU:n 111, 112, 115, 117 ja 118 alustavan lähetystehon. Demodulaatio 15 on koherenttia, jossa pilottisignaali antaa vaihereferenssin.The CDMA modulator in either the RCS or the SU reduces the received signal by suitable processing to eliminate or take advantage of the effects of multipath propagation. The parameters relating to the received power level are used to generate the Automatic Power Control (APC) information, which in turn is transmitted to the other end. The APC information is used to control the transmission power of the Automatic Feedback Control (AFPC) and Automatic Response Power Control (ARPC) links. In addition, each RCS 104, 105, and 110 may perform maintenance power control (MPC), similar to APC, to match the initial transmission power of each SU 111, 112, 115, 117, and 118. Demodulation 15 is coherent, where the pilot signal provides phase reference.
Radioliittymän lähetystehotasoja RCS:n 104 ja SU:uiden 111, 112, 115, 117 ja 118 välillä ohjataan käyttämällä kahta erilaista suljetun silmukan tehonohjausal-goritmia. Automaattien myötätehonohjaus (AFPC) määrittää alaslinkin lähetys-20 tehotason, ja automaattien vastatehonohjaus (ARPC) määrittää ylöslinkin lähe-tystehotason. Looginen ohjauskanava, jolla SU 111 ja RCS 104, esimerkiksi, lähettävät tehonohjausinformaatiota, toimii vähintään 16 kHz:n päivitysnopeu- • · | ;* della. Muut sovellutusmuodot voivat käyttää nopeampaa 32 kHz:n päivitysno- : peutta. Nämä algoritmit varmistavat, että käyttäjän lähetysteho säilyttää hyväkin : 25 syttävän bittivirhesuhteen (BER), ylläpitää järjestelmätehoa minimissä säästä- mään tehoa, ja ylläpitää kaikkien SU:iden 111, 112, 115, 117 ja 118 tehotason, kuten on vastaanotettu RCS:llä 104, melkein samalla tasolla.The radio access transmit power levels between the RCS 104 and the SUs 111, 112, 115, 117 and 118 are controlled using two different closed-loop power control algorithms. The Automatic Feeder Power Control (AFPC) determines the downlink transmit power level, and the Automatic Response Power Control (ARPC) determines the uplink transmit power level. The logical control channel on which the SU 111 and RCS 104, for example, transmit power control information operates at a refresh rate of at least 16 kHz. ; * della. Other embodiments may use a faster 32 kHz refresh rate. These algorithms ensure that the user transmits power well: 25 lit bit error rate (BER), maintains system power to a minimum to conserve power, and maintains the power levels of all SUs 111, 112, 115, 117, and 118 as received by RCS 104, almost at the same level.

Lisäksi järjestelmä sisältää vaihtoehtoisen ylläpitotehoalgoritmin, jota käytetään : ,·. 30 SU:n inaktiivisen moodin aikana. Kun SU 111 on inaktiivinen tai ohjattu teho • · · [·’·] alas säästämään tehoa, yksikkö voi tilapäisesti aktivoida itsensä ja asetella sen » · *!* alustavan lähetystehotasoasetuksen vasteena ylläpitotehonohjaussignaalille i RCS:stä 104. Ylläpitotehosignaali on määritetty RCS:llä 104 mittaamalla SU:n 111 vastaanotettu tehotaso ja senhetkinen järjestelmätehotaso ja laskemalla 35 tarvittava alustava lähetysteho. Menetelmä lyhentää SU:n 111 kanavasaantiai- : kaa, kun se on käännetty päälle alkamaan yhteyden. Menetelmä myös estää • > * SU:n 111 lähetystehotasoa tulemasta liian suureksi ja häiritsemästä muita ka- 7 115810 navia alustavan lähetyksen aikana ennen kuin suljetun silmukan tehonohjaus asettelee lähetystehon muulle kanavan viestiliikenteelle sopivalle tasolle.In addition, the system includes an alternative maintenance power algorithm to use:, ·. 30 during SU inactive mode. When the SU 111 is inactive or power controlled • · · [· '·] down to conserve power, the unit may temporarily activate itself and set it »· *! * The initial transmit power level setting in response to the maintenance power control signal i from RCS 104. The maintenance power signal is determined by RCS 104. measuring the received power level of the SU 111 and the current system power level and calculating 35 the required initial transmit power. The method shortens the SU access time to the 111 when turned on to start a connection. The method also prevents the transmission power levels of the SU> 111 from becoming too high and interfering with other channels during the initial transmission before the closed-loop power control adjusts the transmission power to a level suitable for other channel communication.
RCS 104 saa sen kellon synkronoinnin liitäntälinjasta, kuten, mutta ei rajoitettu-5 na, E1-, T1-, tai HDSL-liitännät. Kukin RCS voi myös generoida sen oman sisäisen kellosignaalin oskillaattorista, jota voidaan säätää globaalin paikannus-järjestelmän (GPS) vastaanottimella. RCS 104 generoi globaalin pilottikoodin kanavalle, jossa on levityskoodi, mutta ei datamodulaatiota, joka voidaan saada kaukaisilla SU:illa 111-118. RCS:n kaikki lähetyskanavat ovat synkronisia pi-10 lottikanavan kanssa, ja koodigeneraattoreiden (ei esitetty) levityskoodivaiheet, joita käytetään logiikkayhteyskanaville RCS:ssä 104 ovat myös synkronisia pi-lottikanavan levityskoodivaiheen kanssa. Samalla tavalla, SU:t 111 - 118, jotka vastaanottavat RCS:n globaalin pilottikoodin, synkronoivat SU:iden koodigeneraattoreiden (ei esitetty) levittävät ja kaventavat koodivaiheet globaalille 15 pilottikoodille.The RCS 104 receives its clock synchronization from an interface line such as, but not limited to, E1, T1, or HDSL. Each RCS can also generate its own internal clock signal from an oscillator that can be controlled by a Global Positioning System (GPS) receiver. The RCS 104 generates a global pilot code for a channel having a spreading code but no data modulation that can be obtained by remote SUs 111-118. All the RCS transmission channels are synchronous with the pi-10 lot channel, and the spreading code steps of the code generators (not shown) used for the logic communication channels in RCS 104 are also synchronous with the pilot channel spreading code phase. Similarly, SUs 111 to 118, which receive the RCS Global Pilot Code, synchronize the spreading and narrowing code steps of the SUs' code generators (not shown) to the Global Pilot Code.
Loogiset yhteyskanavatLogical communication channels
Tunnetun tekniikan "kanavaa” pidetään tavallisesti tietoliikennetienä, joka on 20 osa liitäntää, ja joka voidaan erottaa liitännän muista teistä riippumatta sen sisällöstä. CDMA:n tapauksessa, kuitenkin, erilliset tietoliikennekanavatiet on erotettu vain niiden sisällöllä. Termiä ’looginen kanava’ käytetään erottamaan erilli- * » set datavirrat, jotka ovat loogisesti ekvivalentteja kanaviin konventionaalisessa : mielessä. Kaikki tämän keksinnön loogiset kanavat ja alikanavat on mapattu · 25 yleisiin 64 kilosymbolia sekuntia kohti (ksym/s) QPSK-virtaan. Jotkut kanavat on synkronoitu liittyviin pilottikoodeihin, jotka on generoitu ja suorittavat samanlai-sen toiminnan kuin järjestelmän globaalinen pilottikoodi. Järjestelmän pilottisig-naaleita ei, kuitenkaan, pidetä loogisina kanavina.The prior art "channel" is usually considered to be a communication path that is 20 parts of an interface and can be distinguished from other links in the interface regardless of its content. In the case of CDMA, however, separate communication channel paths are separated only by their content. * »Set data streams that are logically equivalent to channels in the conventional: sense All logical channels and subchannels of this invention are mapped to · 25 generic 64 kiloseconds (ksym / s) QPSK streams, some channels are synchronized with associated pilot codes generated and performs the same function as the system global pilot code, however, system pilot signals are not, however, considered logical channels.
: 30 Useita loogisia yhteyskanavia käytetään RF-yhteyslinkin kautta RCS:n ja SU:n ’«’·] välillä.

Nämä kanavat sisältävät tyypillisesti 115810 8 annetun tyyppistä informaatiota kaikille käyttäjille. Nämä kanavat sisältävät kanavat, joita SU:t käyttävät vahvistamaan järjestelmään pääsyä. Kanavat liitettyjen kanavien (AC) ryhmässä ovat niitä kanavia, jotka on yhdistetty yhteyteen RCS:n ja tietyn SU:n välillä.: 30 Multiple logical communication channels are used via the RF communication link between RCS and SU '' '·]. Each logical communication channel has either a fixed, predefined spreading • code or a dynamically linked spreading code. For both predefined and fixed codes, the code phase is synchronous with the pilot code. Logical connection channels are divided into two groups: the Global Channel (GC) group and the linked: ·. 35 channel (AC) group. The GC group includes channels that are either transmitted on the radio; from base station RCS to all remote SUs or from any SU to base station RCS regardless of the identity of the SU. These channels typically contain 115810 8 given types of information for all users. These channels include the channels used by the SUs to confirm access to the system. Channels in a group of connected channels (AC) are those channels that are connected to the connection between the RCS and a specific SU.

Tehonohjauspower Control
Yleistä 10 Tämän keksinnön tehonohjauspiirrettä käytetään minimoimaan lähetysteho, jota käytetään RCS:n ja minkä tahansa SU:n välillä, jonka kanssa se on yhteydessä. Tehonohjauksen alipiirre, joka päivittää lähetystehon kantajakanavan liitännän aikana, on määritetty automaattisena tehonohjauksena (APC). APC-data on siirretty RCS:stä SU:hun APC:n myötäkanavalla ja SU:sta RCS:een APC:n 15 vastakanavalla. Kun ei ole aktiivista datalinkkiä kahden välillä, ylläpitotehonoh-jauksen alipiirre (MPC) ohjaa SU:n lähetystehoa.General 10 The power control feature of the present invention is used to minimize the transmission power used between the RCS and any SU to which it is communicating. The power control sub-feature that updates the transmit power during carrier channel connection is configured as automatic power control (APC). The APC data is transferred from the RCS to the SU on the APC forward channel and from the SU to the RCS on the APC reverse channel 15. When there is no active data link between the two, the maintenance power control sub-feature (MPC) controls the transmission power of the SU.
Myötä- ja vastan imettyjen kanavien ja vastaglobaalisten kanavien lähetysteho-tasoja ohjataan APC-algoritmilla ylläpitämään riittävä signaaliteho-interferens-20 sikohinatehosuhde (SIR) noissa kanavissa, ja stabiloimaan ja minimoimaan järjestelmän ulostuloteho. Tämä keksintö käyttää suljetun silmukan tehonoh-; jausjärjestelmää, jossa vastaanotin ohjaa siihen liittyvää lähetintä lisäävästi : nostamaan tai laskemaan sen lähetystehoa. Tämä ohjaus johdetaan liittyvään : lähettimeen tehonohjaussignaalin kautta APC-kanavassa. Vastaanotin tekee 25 päätöksen lisätä tai vähentää lähettimen tehoa perustuen kahteen virhesignaa- I *·· liin. Yksi virhesignaali on ilmaisu erosta mitattujen ja vaadittujen kavennettujen :T: signaalitehojen välillä, ja toinen virhesignaali on ilmaisu keskimääräisestä vas taanotetusta kokonaistehosta.The transmit power levels of the forward and newly sucked channels and the counter-global channels are controlled by the APC algorithm to maintain sufficient signal power interference-20 SIR in those channels, and to stabilize and minimize system output power. This invention uses a closed-loop power control; a sensing system in which the receiver controls the associated transmitter in an increasing manner: to increase or decrease its transmit power. This control is conducted to the associated: transmitter via a power control signal in the APC channel. The receiver makes 25 decisions to increase or decrease transmitter power based on two error signals. One error signal is an indication of the difference between the measured and required attenuated: T: signal powers, and the other error signal is an indication of the average total power received.
30 Kuten on käytetty keksinnön kuvatussa sovellutusmuodossa, termiä lähipään ’· tehonohjaus käytetään viittaamaan lähettimen ulostulotehon asettelemiseen • ’·* APC-signaalin, joka on vastaanotettu APC-kanavalla toisesta päästä, mukai- sesti. Tämä tarkoittaa vastatehonohjausta SU:lle ja myötätehonohjausta ja . ··. myötätehonohjausta RCS:lle; ja termiä kaukopää-APC käytetään viittaamaan 35 myötätehonohjaukseen SU:lle ja vastatehonohjausta RCS:lle (asettelemalla yksikön lähetystehoa kanavan vastakkaisessa päässä).As used in the described embodiment of the invention, the term near-end power control is used to refer to the setting of transmitter output power according to an APC signal received on an APC channel at one end. This means counter power control for SU and feed power control and. ··. power control for RCS; and the term far-end APC is used to refer to 35 forward power control for the SU and counter power control for the RCS (by setting the transmit power of the unit at the opposite end of the channel).
9 115810 Säästääkseen tehoa, SU-modeemi päättää siirron ja poiskytkennät odottaessaan puhelua, määritettynä nukkumavaiheena. Nukkumavaihe päättyy herätys-signaaliin SU-ohjaimesta. Vastaten tätä signaalia, SU-modeemin saantipiiri saapuu automaattisesti uudelleensaantivaiheeseen, ja alkaa alaslinkkipilotin 5 saantiprosessin, kuten on kuvattu alla.9 115810 To conserve power, the SU modem terminates transfer and shutdowns while waiting for a call, defined as a sleep phase. The sleep phase ends with an alarm signal from the SU controller. In response to this signal, the SU modem's gain circuit automatically enters the re-acquisition phase, and begins the downlink pilot 5 acquisition process as described below.
Suljetun silmukan tehonohjausalgoritmit Lähipään tehonohjaus sisältää kaksi vaihetta: ensiksi, aseta alustava lähetyste-10 ho; toiseksi, jatkuvasti asettelee lähetystehoa informaation mukaisesti, joka on vastaanotettu kaukopäästä käyttäen APC:tä.Closed-loop Power Control Algorithms Close-end power control includes two steps: First, set the initial transmit-10 ho; second, continuously adjusts the transmission power in accordance with the information received from the remote end using the APC.
SU:Ile, alustava lähetysteho on asetettu minimiarvoon ja sitten nostettu asteittain, esimerkiksi, nopeudella 1 dB/ms, kunnes joko asteittainen ajastin loppuu 15 (ei esitetty) tai RCS vaihtaa vastaavan liikennevaloarvon FBCH:ssa ’’punaiseksi” ilmaisten, että RCS on lukittunut SU:iden lyhyeen pilottisignaaliin (SAXPT). Ajastimen päättyminen aiheuttaa SAXPT:n siirron katkeamisen, ellei liikennevaloarvoa ole asetettu punaiseksi ensin, jossa tapauksessa SU jatkaa asteittain nostaa lähetystehoa, mutta paljon pienemmällä nopeudella kuin en-20 nen "punainen”-signaali oli ilmaistu.For SU, the initial transmit power is set to a minimum value and then incrementally increased, for example, at 1 dB / ms until either the progressive timer expires 15 (not shown) or the RCS changes the corresponding traffic light value in the FBCH to "red" indicating that the RCS is locked SUs Short Pilot Signal (SAXPT). The end of the timer causes the SAXPT transmission to be interrupted unless the traffic light value is set to red first, in which case the SU continues to gradually increase the transmit power, but at a much lower rate than the previous "red" signal was detected.

Yhden bitin signaali edustaa käskyä lisäämään (signaali on loogisesti ylhäällä) tai vähentä-30 mään (signaali on loogisesti alhaalla) liitettyä lähetystehoa. Kuvatussa sovellu-/ , tusmuodossa, 64 kbps APC-datavirtaa ei ole koodattu tai limitetty.The APC signal is transmitted as single-bit signals on the APC channel. A one-bit signal represents an instruction to increase (the signal is logically up) or decrease-30 (the signal is logically low) the transmitted power.

Ylläpitotehonohjaus SU:n nukkumavaiheen aikana, CDMA RF-kanavan interferenssikohinateho 20 vaihtelee. Vaihtoehtona alustavalle edelläkuvatulle tehon asteettaisen noston menetelmälle, tämä keksintö voi sisältää ylläpitotehonohjauspiirin (MPC), joka jaksottain asettelee Slliiden alustavan lähetystehon CDMA-kanavan interfe- .* V renssikohinatehon suhteen.

As an alternative to the preliminary power stepping method described above, the present invention may include a maintenance power control circuit (MPC), which periodically adjusts the Slide initial transmission power in terms of CDMA channel interface. MPC is the process of maintaining the SU transmit power level in the immediate vicinity of the required minimum level of the RCS to detect the signal of the 25 countries SUs. The MPC process compensates for low frequency changes in · the required SU transmission power.
t ♦ I * S·’; Ylläpito-ohjauspiirre käyttää kahta globaalia kanavaa: yhtä kutsutaan status- kanavaksi (STCH) vastalinkillä, ja toista kutsutaan tarkistuskanavaksi (CUCH) : 30 myötälinkillä. Näillä kanavilla lähetetyt signaalit eivät kuljeta dataa eikä niitä ole generoitu samalla tavalla kuin lyhytkoodit, joita käytetään alustavassa tehon T nostossa, on generoitu. STCH- ja CUCH-koodit on generoitu globaalin koodi- ; generaattorin’’varatusta” haarasta.t ♦ I * S · '; The maintenance control feature uses two global channels: one is called the status channel (STCH) on the reverse link, and the other is called the check channel (CUCH): 30 on the forward link. The signals transmitted on these channels do not carry data and are not generated in the same way as the short codes used in the initial power T increase. The STCH and CUCH codes are generated by a global code; generator '' charged 'branch.

Kun SU havaitsee vastauksen RCS:stä, se pienentää sen lähetystehoa tietyllä askelkoolla. Jos SU ei havaitse mitään vastausta RCS:stä 3 ms:n aikana, se lisää sen lähetystehoa askelkoolla. Käyttämällä tätä menetelmää, RCS-vastaus lähetetään tehotasolla, 5 joka on riittävä ylläpitämään 0,99 havaintotodennäköisyyden kaikissa SU:iisa.»Tl I · •» i t · 35 The MPC process is as follows. At random intervals, the SU sends a symbol • I ·; periodic spreading code on a 3 ms status channel (STCH). If the RCS detects the sequence, it responds by transmitting the symbol length code sequence 11115810 for the next 3 ms on the check channel (CUCH). When the SU detects a response from the RCS, it reduces its transmit power by a certain step size. If the SU does not detect any response from the RCS within 3 ms, it will increase its transmit power by the step size. Using this method, the RCS response is transmitted at a power level 5 sufficient to maintain a 0.99 detection probability across all SUs.
Liikennekuorman muutoksen nopeus ja aktiivisten käyttäjien määrä on suhteessa CDMA-kanavan kokonaisinterferenssikohinatehoon. Ylläpitotehon päivitys-signaalin päivitysnopeus ja askelkoko määritetään tälle keksinnölle käyttämällä 10 yhteysteorian alalla hyvin tunnettuja jonotusteoriamenetelmiä. Mallintamalla puhelun alkuperäprosessin eksponentiaalisena satunnaismuuttujana keskimäärin 6,0 min:a, numeerinen laskenta näyttää, että SU:n ylläpitotehotaso pitäisi päivittää kerran joka 10:s sekunti tai vähemmän kyetäkseen seuraamaan muutoksia interferenssitasossa käyttämällä 0,5 dB:n askelkokoa.

Ylläpitotehon 20 asettelu suoritetaan jaksottain SU:lla, joka muuttaa nukkumavaiheesta valve-vaiheeseen ja suorittaa MPC-prosessin.

The refresh rate and step size of the maintenance power update signal are determined for the present invention using the queuing theory methods well known in the art of connection theory. By modeling the call origin process as an exponential random variable averaging 6.0 min, numerical computation shows that the SU maintenance power level should be updated once every 10 seconds or less to be able to track changes in the interference level using a 0.5 dB step size. By modeling the pu-15 call origin process as a Poisson random variable with exponential mean arrival times, an arrival rate of 2x1ο-4 seconds per user, a service rate of 1/360 seconds, and a total subscriber population of 600 in the RCS service area, sufficient when using a step of 0.5 dB. The adjustment of the maintenance power 20 is performed periodically by the SU, which changes from the sleep phase to the wake phase and executes the MPC process. Similarly, the process for MPC feature is ► · 5! shown in Fig. 2 and is as follows: First, in step 201, the signals are switched **. * switched between the SU and the RCS maintaining a transmit power level close to the required: V level for detection: the SU periodically transmits a symbol length spreading code • · ·; ·: 25 on the STCH, and the RCS periodically transmits the symbol length spreading code: · * on the CUCH in response.

Siten, STCH-viestien lähetysteho SU:sta asetetaan perustuen RCS-vastaukseen jaksottain, ja CUCH-viestien lähetysteho RCS:stä on kiinteä.Thus, the transmission power of the STCH messages from the SU is set periodically based on the RCS response, and the transmission power of the CUCH messages from the RCS is fixed.
Tehonohjaussignaalin mappaus loogisiin kanaviin APC:lle 5Power control signal mapping to logical channels for APC 5
Tehonohjaussignaalit on mapattu tiettyihin loogisiin kanaviin ohjaamaan myötä-ja vastaliittyneiden kanavien lähetystehotasot. Vastaglobaalikanavia ohjataan myös APC-alogitmilla ylläpitämään riittävä signaalitehon ja interferenssiko-hinatehon suhde (SIR) noissa vastakanavissa, ja stabiloimaan ja minimoimaan 10 järjestelmän ulostuloteho. Tämä keksintö käyttää suljetun silmukan tehonoh-jausmenetelmää, jossa vastaanotin jaksottain päättää lisäävästi nostaa tai alentaa lähettimen ulostulotehoa toisessa päässä. Menetelmä myös kuljettaa päätöksen takaisin vastaavaan lähettimeen.The power control signals are mapped to certain logical channels to control the transmit power levels of the forward and reverse channels. The anti-global channels are also controlled by the APC alogit to maintain a sufficient signal power to interference noise power (SIR) in those counter channels, and to stabilize and minimize the output power of the system. The present invention employs a closed-loop power control method, wherein the receiver periodically decides to incrementally increase or decrease transmitter output power at one end. The method also carries the decision back to the corresponding transmitter.

5 APC-parametrit APC-informaatio on aina kuljetettu yhtenä informaatiobittinä, ja APC:n datano-peus on ekvivalentti APC:n päivitysnopeuteen. APC:n päivitysnopeus on 64 10 kb/s. Tämä nopeus on riittävän suuri sisällyttämään odotetut Rayleighin ja Dopplerin häipymät, ja sallii suhteellisen suuren (~0,2) bittivirhenopeuden (BER) ylöslinkin ja alaslinkin APC-kanavissa, mikä minimoi APC:lle annetun kapasiteetin.APC Parameters APC information is always transported in a single bit of information, and the APC data rate is equivalent to the APC update rate. The APC has a refresh rate of 64 10 kbps. This rate is high enough to include the expected Rayleigh and Doppler fades, and allows a relatively high (~ 0.2) bit error rate (BER) in uplink and downlink APC channels, which minimizes the capacity given to the APC.

Te-honohjauksen dynaaminen alue on 70 dB vastalinkillä ja 12 dB myötälinkillä tämän järjestelmän esimerkinomaiselle sovellutusmuodolle.The power increase / decrease in 15 APC bits is nominally between 0.1 and 0.001 dB.

35 Tämän keksinnön esimerkinomaisen sovellutusmuodon tehonohjausjärjestelmä on esitetty kuviossa 5. Kuten on esitetty, lähetettyä tehoa asettelemaan käytetty piiri on samanlainen RCS:n (esitetty RCS:n tehonohjausmoduulina 501) ja SU:n 16 115810 (esitetty SU:n tehonohjausmoduulina 502) kanssa. Alkaen RCS:n tehonoh-jausmodulin 501 kanssa vastalinkin RF-kanavasignaali on vastaanotettu RF-antennissa ja demoduloitu tuottamaan CDMA:n vastasignaalin RMCFI, jota on käytetty vaihtelevan vahvistuksen vahvistimeen (VGA1) 510. VGA1 510:n 5 ulostulosignaali on annettu automaattisen vahvistuksen ohjauksen (AGC) piiriin 511, joka tuottaa vaihtelevan vahvistuksen vahvistimen signaalin VGA1 510:een. Tämä signaali ylläpitää VGA1 510:n ulostulosignaalin tason lähes vakioarvossa. VGA1:n ulostulosignaali on kavennettu kavennus-demultiplekserillä (demux) 512, joka tuottaa kavennetun käyttäjäviestisignaalin MS ja APC:n 10 myötäbitin. APC:n myötäbittiä on käytetty integraation in 513 tuottamaan APC:n myötäohjaussignaalin. APC:n myötäohjaussignaali ohjaa myötälinkkiä VGA2 514 ja ylläpitää myötälinkin RF-kanavasignaalin yhteydelle välttämättömällä minimitasolla.The power control system of the exemplary embodiment of the present invention is shown in Figure 5. As shown, the circuit used to set the transmitted power is similar to the RCS (shown as RCS power control module 501) and SU 16115810 (shown as SU power control module 502). Starting with the RCS power control module 501, the reverse link RF channel signal is received in the RF antenna and demodulated to produce the CDMA counter signal RMCFI used in the Variable Gain Amplifier (VGA1) 510. The VGA1 510 5 output signal is provided by the automatic gain control ( AGC) to a circuit 511 that produces a variable gain amplifier signal to VGA1510. This signal maintains the output signal level of the VGA1 510 at a nearly constant value. The VGA1 output signal is attenuated by a demux demultiplexer (demux) 512, which produces a attenuated user messaging signal MS and an APC 10 bit. The APC forward bit has been used to integrate in 513 to produce the APC forward control signal. The APC forward control signal controls the forward link VGA2 514 and maintains the forward link at the minimum level necessary for the RF channel signal.
15 RCS:n tehomodulin 501 kavennetun käyttäjäviestisignaalin signaaliteho mitataan tehonmittauspiirillä 515 tuottamaan signaalin tehon ilmaisun. VGA1:n ulostulo on myös kavennettu AUX-kaventimella, joka kaventaa signaalin käyttämällä korreloimatonta levityskoodia, ja siten saa kavennetun kohinasignaalin. Tämän signaalin tehonmittaus on kerrottu 1:llä plus vaadittava signaali-kohina-20 suhde (SNRr) muodostamaan kynnyssignaalin S1. Ero kavennetun signaalite-hon ja kynnysarvon S1 välillä tuotetaan vähentimellä 516. Tämä ero on vir-; f hesignaali ES1, joka on virhesignaali liittyen tiettyyn SU:n lähetystehotasoon.The signal power of the attenuated user communication signal of the RCS power module 501 is measured by a power measuring circuit 515 to provide signal power detection. The output of the VGA1 is also attenuated by an AUX attenuator, which attenuates the signal using an uncorrelated spreading code, and thus receives a attenuated noise signal. The power measurement of this signal is multiplied by 1 plus the required signal-to-noise ratio (SNRr) to form the threshold signal S1. The difference between the reduced signal power and the threshold S1 is produced by the subtractor 516. This difference is vir; f signal ES1, which is an error signal associated with a particular SU transmission power level.

Skaalauspiirin 25 517 ulostulosignaali on skaalattu järjestelmätehon tasosignaali SP1. Kynnyslas- kentalogiikka 518 laskee järjestelmäsignaalikynnyksen SST arvon RCS:n käyt-täjäkanavatehon datasignaalista (RCSUSR). Skaalatun järjestelmätehotasosig-naalin, SP1, komplementtia ja järjestelmän signaalitehon kynnysarvoa SST käytetään summaimeen 519, joka tuottaa toisen virhesignaalin ES2. Tämä vir-30 hesignaali on kaikkien aktiivisten SU:iden järjestelmälähetystehotasoon. Sisääntulon virhesignaalit ES1 ja ES2 on yhdistetty yhdistäjässä 520 tuottamaan yhdistetyn virhesignaalisisääntulon deltamodulaattoriin (DM1) 521, ja DM1:n :,,,ί ulostulosignaali on APC:n vastabittivirran signaali, jolla on bittejä arvoltaan +1 . · · ·. tai -1, joka tälle keksinnölle lähetetään 64 kb/s:n signaalina.··: Similarly, the control signal of the VGA1 510 has been applied to the speed scaling circuit 517 to reduce the rate of the control signal to the VGA1 510. The output signal of the scaling circuit 25 517 is a scaled system power level signal SP1. Threshold calculator logic 518 calculates a system signal threshold SST from the RCS user channel power data signal (RCSUSR). The complement of the scaled system power level signal, SP1, and the system signal power threshold SST are applied to adder 519, which produces a second error signal ES2. This vir-30 signal is at the system transmit power level of all active SUs. The input error signals ES1 and ES2 are combined at combiner 520 to produce a combined error signal input to a deltamodulator (DM1) 521, and the output signal of DM1 :,, π is an APC counter-current signal having bits of +1. · · ·. or -1, which is transmitted to the present invention as a 64 kbps signal.

VGA3 540:n ulostulosignaali on kavennettu 15 kavennusdemuxilla 542, joka tuottaa kavennetun käyttäjäviestisignaalin SUMS ja APC:n vastabitin.

This signal is applied to a variable gain amplifier (VGA3) 540. The VGA3 output signal is adapted to an automatic gain control circuit (AGC) 541 which produces a variable gain amplifier control signal for the VGA3 540. This signal maintains the output signal level of VGA3 at a nearly constant level.

Threshold S3 is calculated by multiplying a 35-bar reduced power measurement obtained from the AUX attenuator by 1 plus the desired signal-to-noise ratio SNRr. The AUX attenuator reduces the signal by using an uncorrelated spreading code, so its output signal is an indication of reduced power 19 115810. Similarly, the VGA1 control signal is adapted to a speed scaling circuit 609 to reduce the rate of the VGA1 control signal to produce a scaled system power level signal SP2. Threshold Calculation Logic 610 determines the Initial System Signal Threshold (ISST), which is calculated from the 5 user channel power data signals (IRCSUSR). The complement and (ISST) of the scaled system power level signal SP2 is applied to an adder 611 which produces a second error signal ES6 which is an error signal relative to the system transmit power level of all active SUs. The ISST value is the desired transmit power for a system with a particular configuration. The input error signals ES510 and ES6 are combined in adder 612 to produce a combined error signal input to a delta modulator (DM3) 613.

5 Järjestelmän kapasiteetin hallinta Tämän keksinnön järjestelmän kapasiteetin hallinta-algoritmi optimoi käyttäjän maksimikapasiteetin RCS-alueelle, nimettynä soluksi. Kun SU tulee maksimilä-hetystehon tietyllä arvolla, SU lähettää hälytysviestin RCSJIe. RCS asettaa lii-10 kennevalot, jotka ohjaavat pääsyä järjestelmään, ’’punaiseksi”, joka, kuten on kuvattu aikaisemmin, on lippu, joka SU:iden pääsyn. Tämä tilanne säilyy voimassa, kunnes hälyttävä SU päättää puhelunsa, tai kunnes hälyttävän SU:n lähetysteho, mitattuna SU:llä, on pienempi arvo kuin maksimilähetysteho. Kun useat SU:t lähettävät hälytysviestejä, tilanne säiyy voimassa, kunnes joko kaikki 15 puhelut hälyttävistä SU:ista päättyvät, tai kunnes hälyttävän SU:n lähetysteho, mitattuna SU:ssä, on pienempi arvo kuin maksimilähetysteho. Vaihtoehtoinen sovellutusmuoto mittaa bittivirhenopeusmittaukset myötävirhekorjauksen (FEC) dekooderilta, ja pitää RCS:n liikennevalot ’’punaisena”, kunnes bittivirheen määrä on pienempi kuin ennaltamäärätty arvo.5 System Capacity Management The system capacity management algorithm of the present invention optimizes a user's maximum capacity in the RCS area, designated as a cell. When the SU arrives at a certain maximum transmit power, the SU sends an alarm message to the RCSJ. The RCS sets the li-10 kennel lights that control access to the system, "red", which, as previously described, is the flag that accesses the SUs. This situation remains in effect until the alert SU terminates its call, or until the transmit power of the alert SU, as measured by the SU, is less than the maximum transmit power. When multiple SUs send alert messages, the situation remains in effect until either all 15 calls from the alert SUs end, or until the transmit power of the alert SU, as measured at the SU, is less than the maximum transmit power. An alternative embodiment measures bit error rate measurements from a forward error correction (FEC) decoder and keeps the RCS traffic lights "" red "until the bit error rate is less than a predetermined value.
20 Tämän keksinnön estostrategia sisältää menetelmän, joka käyttää tehonoh-jausinformaatiota, joka on lähetetty RCS:ltä SU:hun, ja vastaanotetut tehon : mittaukset RCS:llä. RCS mittaa sen lähetystehotason, ilmaisee, että maksimiar- ; vo on saavutettu, ja määrittää, milloin estää uudet käyttäjät. SU, joka valmiste- 25 lee tuloa järjestelmään, estää itsensä, jos SU saavuttaa maksimilähetystehon |’ ennen kantajakanavan nimeämisen onnistunutta suoritusta.The blocking strategy of the present invention includes a method using power control information transmitted from the RCS to the SU and received power: measurements by the RCS. The RCS measures its transmit power level, indicating that the max. vo is reached and determine when to block new users. The SU preparing to enter the system will prevent itself if the SU reaches maximum transmission power? 'Before successfully carrying the carrier channel.
* Kullakin lisäkäyttäjällä järjestelmässä on vaikutus lisätä kohinatasoa kaikille muille käyttäjille, joka vähentää signaali-kohinasuhdetta (SNR), jonka kukin v.: 30 käyttäjä kokee. Tehonohjausalgoritmi ylläpitää halutun SNR:n kullekin käyttä- v ; jälle. Siksi, minkä tahansa muiden rajoitusten puutteessa, uuden käyttäjän li- : säämisellä on vaon transienttinen vaikutus ja haluttu SNR saavutetaan uudel- .···! leen.* Each additional user in the system has the effect of increasing the noise level for all other users, reducing the signal-to-noise ratio (SNR) experienced by each user: 30. The power control algorithm maintains the desired SNR for each user; jälle. Therefore, in the absence of any other limitations, adding a new user will have the transient effect of a trap and the desired SNR will be achieved again. Lee's.
35 Lähetystehon mittaus RCS:ssä tehdään mittaamalla joko peruskaistan yhdiste-tyn signaalin tehollisarvo (rms) tai mittaamalla RF-signaalin lähetysteho ja syöttämällä se takaisin digitaalisiin ohjauspiireihin. Lähetystehon mittaus voi- 21 115810 daan myös tehdä SU:illa määrittämään, onko yksikkö saavuttanut sen maksi-milähetystehon. SU:n lähetystehotaso on määritetty mittaamalla RF-vahvistimen ohjaussignaali, ja skaalaamalla arvo perustuen palvelutyyppiin, kuten pelkkänä vanhana puhelinpalveluna (POTS), FAX, tai integroitujen pal-5 velujen digitaaliverkko (ISDN).35 The transmit power measurement in the RCS is made by measuring either the baseband combined signal effective value (rms) or by measuring the transmit power of the RF signal and feeding it back to the digital control circuits. The transmit power measurement may also be performed by the SUs to determine whether the unit has reached its maximum transmit power. The SU transmission power level is determined by measuring the control signal of the RF amplifier, and scaling the value based on a type of service, such as legacy telephone service only (POTS), FAX, or Integrated Services Digital Network (ISDN).
Informaatio, että SU on saavuttanut maksimitehon, lähetetään RCS:lle SU:lla viestissä nimetyillä kanavilla. RCS myös määrittää ehdon mittaamalla vasta-APC:n muutokset, koska, jos RCS lähettää APC-viestit SU:lle lisäämään SU.n 10 lähetystehoa, ja SU:n lähetysteho mitattuna RCS:ssä ei kasva, SU on saavuttanut maksimilähetystehon.Information that the SU has reached its maximum power is sent to the RCS by the SU on the designated channels in the message. The RCS also determines the condition by measuring the changes in the counter-APC because, if the RCS sends the APC messages to the SU to increase the 10 transmission power of the SU, and the SU transmission power measured in the RCS does not increase, the SU has reached its maximum transmission power.
RCS ei käytä liikennevaloja estämään uusia käyttäjiä, jotka ovat lopettaneet ylösnousun käyttämällä lyhytkoodeja. Nämä käyttäjät estetään kieltämällä niiltä 15 soittoääni ja antamalla niille ajan loppu. RCS lähettää kaikki 1:t (mene alas-käskyt) APC-kanavalla pakottamaan SU:n pienentämään sen lähetystehoa. RCS myös lähettää joko ei-CTCH-viestin tai viestin, jossa on väärä osoite, joka pakottaisi FSU:n hylkäämään pääsyproseduurin ja aloittamaan alusta. SU ei aloita hankintaprosessia välittömästi, koska liikennevalot ovat punaiset.The RCS does not use traffic lights to block new users who have stopped ascending using short codes. These users are blocked by denying them 15 ringtones and allowing them to run out of time. RCS transmits all 1's (go-down commands) on the APC channel to force the SU to reduce its transmit power. RCS also sends either a non-CTCH message or a message with the wrong address that would force FSU to reject the access procedure and start over. SU does not start the procurement process immediately because the traffic lights are red.
2020
Kun RCS saavuttaa sen lähetystehorajan, se pitää yllä eston samalla tavalla ·' kuin SU:n saavuttaessa sen lähetystehorajan. RCS kytkee pois kaikki liikenne- L: : valot FBCH:lla, alkaa lähettää 1 APC-bittejä (mene alas-käskyjä) niille käyttäjil- ;,· · le, jotka ovat suorittaneet loppuun niiden lyhyen koodin ylösnoston, mutta joille ·:* 25 ei vielä ole annettu soittoääntä, ja joko lähettää ei-CTCH-viestiä näille käyttäjille tai lähettää viestit väärillä osoitteilla pakottamaan ne hylkäämään pääsyproses-:·. sin.When the RCS reaches its transmit power limit, it maintains blocking in the same manner as when the SU reaches its transmit power limit. The RCS turns off all traffic L:: lights on the FBCH, starts sending 1 APC bits (go-down commands) to users who have completed their short code-up but for whom:: * 25 has not yet given a ringtone, and either send a non-CTCH message to these users or send messages with the wrong addresses to force them to reject the access process-: ·. process.
.... SU:n itse-estoalgoritmi on seuraava. Kun SU alkaa lähettää AXCH.ta, APC sen 30 tehonohjaustoiminnan käyttämällä AXCH:ta ja SU:n lähetysteho kasvaa. Kun * lähetysteho kasvaa APC:n ohjauksen aikana, sitä valvotaan SU-ohjaimella. Jos :,··· lähetystehotaso on saavutettu, SU hylkää pääsyproseduurin ja aloittaa alusta..... The SU self-blocking algorithm is as follows. When the SU begins transmitting the AXCH, the APC uses its power control operation 30 to operate the AXCH and the transmission power of the SU increases. As * transmission power increases during APC control, it is monitored by the SU controller. If:, ··· transmit power level is reached, the SU discards the access procedure and starts over.
